The suspect in Saturday's mass shooting
at a Pittsburgh synagogue is a 46-year-old local man named Robert Bowers who posted virulent anti-Semitic messages on social media filled with slurs and conspiracy theories.

Two hours before the gunman burst into the synagogue and opened fire during a Shabbat religious service, Bowers posted on chat site Gab.com about the Hebrew Immigrant Aid Society (HIAS), a non-profit that helps Jewish refugees relocate to the United States. The organization says it is guided by Jewish values and history.

"HIAS likes to bring invaders in that kill our people. I can't sit by and watch my people get slaughtered. Screw your optics, I'm going in," wrote Bowers, a described as a white male, heavy set, with a beard.

HIAS President and CEO Mark Hetfield said he wasn't aware of the shooter's "obsession with HIAS until this morning."

The gunman also reportedly shouted anti-Semitic phrases during the shooting, which left 11 people dead and five wounded, including four police officers.

The suspect, a Pittsburgh resident, was shot and in fair condition at a hospital, authorities said.

Gab.com said in a statement that when it learned of the shooting suspect's profile on its site, it took "swift and proactive" action to contact law enforcement immediately.

Gab, which promotes itself as a free-speech alternative to the more heavily policed Twitter, said it backed up the user data and suspended the account, then told the Federal Bureau of Investigation about the data held by the company.

"Gab unequivocally disavows and condemns all acts of terrorism and violence," the company's statement said.

Robert Bowers

Bower has an active firearms license and has made at least six known gun purchases since 1996, a law enforcement official familiar with the investigation told CNN. He did not have a criminal record and was not known to police, law enforcement officials said on Saturday.

An archive of Bower's posts since he joined the site in January appeared to show an angry, anti-Semitic man who shared messages such as: "Daily Reminder: Diversity means chasing down the last white person."

About a month ago he posted pictures showing what appeared to the results of his target practice at a shooting range, and a collection of three handguns that he called his "glock family."

Police said the suspect had three handguns and an assault-style rife at the shooting. It's unclear whether they were the same handguns as the ones in the photo.

Bowers, who is a registered voter with "no affiliation" in Allegheny County, Pennsylvania, took aim in one post at US President Donald Trump, accusing him of being a "globalist" who did nothing to stop the "infestation" of the United States by Jews.

"For the record, I did not vote for him nor have I owned, worn or even touched a MAGA hat," he wrote. MAGA is an acronym for Make America Great Again that is frequently used by Trump.
